Oil is on track for a second yearly gain after the Organization of Petroleum Exporting Countries and partners including Russia agreed to extend supply cuts through all of next year. Output from the group won’t fully rebound when the deal ends, according to Energy Aspects Ltd. Saudi Arabia will remain “proactive” about managing global crude supplies if the international benchmark, Brent crude, dips below $60 a barrel, said Amrita Sen, Energy Aspects’ chief oil market analyst.

West Texas Intermediate for January delivery rose 73 cents to settle at $56.69 a barrel on the New York Mercantile Exchange. Total volume traded was about 25 percent below the 100-day average.

Brent for February settlement added 98 cents to end the session at $62.20 on the London-based ICE Futures Europe exchange. The global benchmark traded at a premium of $5.45 to February WTI.

U.S. gasoline inventories rose by 6.78 million barrels last week, the biggest increase since January, while crude stockpiles slipped by 5.61 million, the EIA reported on Wednesday. Oil production expanded to 9.71 million barrels a day, the highest level in weekly data compiled by the EIA since 1983.

“The risk of further shale growth and domestic production growth, which is what we saw Wednesday, is a bigger negative factor that’s looming in the coming weeks,” Haworth said. “But for now, the market is really waiting to see data and otherwise that bullish tenor is staying.”
